Public bug reported:
Ubuntu 25.10/questing python3 problem with normal updates
** description
about three times per day I run the following
> snap refresh;apt update; apt autoremove ; apt autoclean ; apt full-
upgrade ; fastfetch
to update this system, i have package issues (again, not the first time
this cycle; though also experienced this late in the plucky cycle)
Current install was made using
root@d7050-next:~# cat /var/log/installer/media-info
Lubuntu 25.10 "Questing Quokka" - Daily amd64 (20250603)
so this isn't an old install; but issue seems to keep re-occurring
** apt -f install output
root@d7050-next:~# apt -f install

** details of install
this install was made with lubuntu media; package dep clashes
(initramfs/dracut from memory) caused me to to skip adding xubuntu-
desktop; but in time I added ubuntu-desktop to system.. two days later I
have package issues (that I noticed)
I don't believe I've done anything to cause this; but this is at least
the fifth time I've experienced this since April 2025. Re-install the
system and no issues; yet python3 type change occurs & problems again??
(alas as fastfetch is run instead of neofetch (more lines of output) I'm
less likely to notice errors that scroll up off my usual window where I
perform updates).
